therein and having the plane face 10 resting in the wheels 20 when the cylinder is revolved. The cylinder is provided with an opening 11a which is provided with the sliding door 11. This door is provided with the lug 12 having a beveled head. The door 11 moves in door guides 14 made up of the strips 15 secured to the cylinder. Two spring bars 16 are secured to the cylinder, said spring bars having the bevel lugs 17 which are adapted to slide over and engage the bevel lugs 18 on the door 11. The cylinder is also provided with the enlargements 19 at opposite ends of said c linder for the purpose fully hereinafter set forth.

The cylinder 6 is normally supported by the wheels 20 mounted on the shaft 22 and idler axle 23. Formed on said wheels are the gears 21 which engage the gear-teeth 10 formed on the cylinder 6 and by means of which rotary movement is imparted to said cylinder. On the shaft 22 is the loose gear 24 with which a suitable sliding clutch 25 is adapted to' engage, said clutch being provided with the clutch ring 26.

Mounted on the truck is the motor 27 which has on its shaft the pinion 28 adapted to engage with the gear wheel 29 on the To all 'whom t may concern Be it known that I, Ross M. BioxLnY, a resident of Pittsburgh, in the count-y of Allegheny and State `of Pennsylvania, have invented a new and useful Improvement in Batch-Mixers; and I do hereby declare the following to be av full, clear, and exact 1description thereof.

My invention relates to mixers adapted to be used in connection with the mixing of a batch in the manufacture of glass, although I do not wish to restrict myself to any particular use.

The object ofmy invention is to provide a rotary mixer which may be brought up to position beneath the hoppers containing the ingredients to be mixed to receive and weigh the same, and then be conveyed to the next hopper to receive and weigh a certain portion of another ingredient, and so on, the mixing of the materials taking place if desired, as the apparatus moves to the point of use, thereby saving a great deal of time and labor.

To these ends my invention comprises the novel features hereinafter set forth and claimed.

In the accompanying drawing Figure 1 is a. Side elevation 0f my improved batch Shaft 30: The pinion 3l. O11 13116 Shaft 30 11- mixer; Fig. 2 is a plan view partly in secgages with the gear wheel 32 on the axle 32a.

This gear wheel 32 is loose on said axle and a suitable sliding clutch 33 on said axle is adapted to be thrown into engagement with said gear wheel. The clutch 33 is provided with the clutch ring 34. Bifurcated rods 35 and 36 engage the clutch rings 26 and34, respectively, said rods being pivoted at 35a and 361 to the frame 5. A link 37 connects tion showing the rotary cylinder in dotted lines; Fig. 3 is an enlarged detail partly in cross section of the rotary cylinder and the mechanism for opening and closing the door; Fig. 4 is a bottom view of the cylinder; Fig. 5 is a sectional detail of a port-ion of the cylinder; Fig. 6 is an enlarged detail of the trip mechanism for opening and closing the door; Fig. 7 is a detail; and Fig. 8 the rod 35 to the bell crank 38 and connected is an end view; and Figs. 9, 10 and 11 are to said bell crank 1s the operating rod 39. A link 40 connects' the rod 36 to the bell crank detail views.

In the drawing the numeral 2 designates a suitable truck provided with the wheels 3 adapted to travel on the track 4. Erected on the truck 2 is the frame 5 which is made-up of angle bars suitably riveted together and braced to make a substantial structure. The mixing cylinder 6 which is carried by said truck 2 may be built up in any suitable manner braced internally by the mixing blades 7, and provided with the trunnions 8. Secured to the circumference of the cylinder 6 are the rings 9 with the gear-teeth 10 formed 41 and to said bell crank is connected the operating ro 42. These operating rods extend to the forward end of the truck and are supported by the bracket 44. A circular guide bar 43 is provided for the bell cranks 38 and 41.

Channel bars 45 extend longitudinally of the frame, said channel bars being connecte 'by the shafts 46 and 47 to form a frame. Levers 48 and 49 are connected to the shafts 46 and 47, respectively, at opposite ends 'thereof. An arm 50 is secured to one end of the y engage the eye bolts S. Links 61 connect shown in Fig. is operated by a lever 70d, said lever passing through the slot e in the angle-plate 70f. Notches 70g are formed in the lever 70d and one of said notches engages the angle-plate according as said trig- 70 ger engages said rim-gear or is disengaged therefrom.

Connected to one end of the equalizing bars 63 are the links 80 Which are connected up to the arm 31 pivoted in the eye bolt 82 75 secured to the frame 5. The opposite end of the arm 81 is connected by links 83 to the scale beam 84, Which is balanced on the standard 35. This scale beam is inclosed Within the scale beam box S6. I have not deemed it necessary to illustrate in detail all the Weighing mechanism as that may be of any desirable form and forms no part of my present invention.

My improved apparatus is adapted to 35 travel beneath the hoppers 87 Which are adapted to discharge the material from the bins above. These hoppers are provided With gates 83 Which are curved and adapted to move into the arc of a circle upon the ce1 90 tral shafts 89. On said shafts are the intermeshing gear Wheels so that when one shaft is rotated to open one gate the other shaft will be rotated in the opposite direction and the other gate opened also. Connected to the gate 38 is the rod 907 said rod .having secured to its outer end the loop 91. rlkhis loop is adapted to engage the arm 92 to the rocking rod 93 extending longitudinally of the ma chine and supported by the frame. At one end of the rod 93 isthe arm 9&1 which is connected up to the rod 95 operated by the lever 96. By operat-ing the lever 96 the rod 93 is rocked and the arm 92 moves so as to operate to open the doors to permit the material to discharge into the cylinder, as fully hereinafter set forth. The arm 92 is provided With the angular finger 97 Which is adapted to guide the arm 92 into engagement With the loop 91 on the lever 90. 110

Carried by the frame 5 are the trolleys 93 Which are adapted to engage the conductors 99 carried in the conduits 100 supported by tracks 101 on the side Wall. The truck or carriage may be provided With an ordinary controller 102.

To provide for the braking of the Wheels 3 of the truck as Well as the Wheels 20 which support and rotate the cylinder, I provide in one instance the lever 103 which is pro- 120 vided at its outer end with the pedal 104A. The opposite end of said lever is secured to the rock shaft 105. At opposite ends of said shaft 105 are the arms 106 which carry the brake-shoes 107 adapted to engage the 125 Wheels 3. A second lever 109 has the treadle 111. This lever is loosely secured to the shaft 105, and has the arms 112 With brakeshoe 113 adapted to engage the Wheels 20.

hen my improved mixer is in use in a 13o shaft 46 and at thc upper end of said arm is the threaded nut 51. Secured to one of the ends of the shaft 47 is an arm 52 provided with a threaded nut A rod 53a has threaded portions 53b and 53. The tlxeaded portion 53b is threaded in one direction and engages the nut517 While the threaded portion 53C is threaded in the opposite direc- V tion and engages the nut 53. The outer end of the rod 53a is supported by the plate 55 on the frame and to the outer end of said rod is secured the hand Wheel 54.

A scale beam 56 is connected to a shaft 57 and said shaft 57 is suspended from eye bolts 58 secured in the frame 5. Castings 59 are shrunk on the shaft 57 at opposite ends thereof and rings 60 in said castings the castings 59 to levers Z19. The opposite end of the scale beam 56 is connected by the link 62 to the equalizing bar 63. A link 64 connect-s the scale beam 56 to the shaft 65. The shaft 65 has the casting 66 shrunk on its ends. Eye bolts 67 are secured in the angle bar 68 connected to the frame 5. Links 69 connect the eye bolts 67 With the castings 66 on the shaft 65. Links 70 connect castings 66 With the levers 4S. A short scale beam 7l is connected to the shaft 65 at one end and at its opposite end to the scale beam 56 by means of the link 72. Chairs 73 are secured to the channels 43 to form supports or rests for the trunnions 8 when the cylinder is rotated in the manner hereinafter set forth. Sway rods 45a are connected to the angles 45h and to the upright channels 45 of the main frame. Like sway-rods 45d are connected to the angles Al5e and the angles 45f of the main frame. These sway-rods control the lateral and longitudinal movement of the channels-A5.

Mounted on the frame is the shaft 74C adapted to rock in its bearings 75. On said shaft is the gate closing lever 76. At one side of said lever is the trip arm 76a. At the outer end of the shaft 74 is the arm 77 to Which is attached the inner end of trip link 78 Which is supported at its forward end by brackets 79. Connected to the shaft 74 is the arm 74a which is connected by the spring 74h to the frame. This spring returns said shaft to its normal position.

To open the gate I provide the dog 76b which is adapted to be moved into the path of the lug 12 on the gate. rlhis dog is normally held out of operative position by the spring 76C. On the rock-shaft 76d which carries the dog 7 6b is the trip-lever 76c which is in the path of the enlargement 19. An arm 76f is secured to the shaft 76d and an operating rod 76g is connected to the arm 7 6f provided With the handle 7 611. A trigger 70a is pivoted to the frame at 7 0b, said trigger being adapted to engage the notch 70c formed in the rirn-gear 9. This trigger as until it rests again on the wheels 20. The trigger 7 OL is now released from the rimgear. In order to close the gate or door 11 power is applied to rotate said cylinder clock-wise and the lever 7 3 is drawn toward 70 the operator which brings the hook on lower end of lever 76 in the path of the lug 12. As said cylinder rotates the gate 11 'is moved over the opening 11v until the spring arm 16 slips between the lugs 17 and the 75 door is locked. Just at the time that this takes place one of the safety lugs or enlargements 19 comes into engagement with one of the trip arms 7 6'0L which acts to rock the shaft 74 and throw the lever 76 to an inop- 80 erative position. This allows the cylinder to continue to rotate with the door in its closed position. The safety lug 19 insures the disengagement of the lever 76 from the lug 12. It does not make any difference 85 how long the operator may hold the lever 7 3 in its forward position he cannot do more than close the gate. Evenif in reversing the direction of rotation of the cylinder he should by mistake pull on the lever 7 3 no 90 damage can result as the curve on the point of the lever 76 allows it to slide over the lug onthe gate.4 After the door is closed the car is then moved to the point where the cylinder is to be discharged overa suit- 95 able bin or receptacle located between the tracks, .and the cylinder may be rotated for a suitable interval until the thorough ad mixture of the ingredients has taken place.

A part of said rotation may take place dur- 100 ing transportation of said mixer if desired. Vhen the car has been brought to a standstill the cylinder is rotated counter-clockwise and the operator pushes in the rod 7 6g which brings hook on dogl 76b in path of lug 105 12. This will arrest the lug 12 and the gate until the enlargement 19 strikes the trip-arm 76@l and said dog 76a is thrown out of englass factory for mixing the batch the car is run along the track'by the motor until 'it arrives at the sand-hopper of the overhea sand-bin. The operator then grasps the handle of the rod 42 and throws the clutch 34 out of engagement with the gear wheel 32 on the axle 32a. This brings the car to a standstill. The operator may also employ the brake lever 103 to aid in stopping the car at the proper point. The car is stopped in such position that when the operator then moves the lever 96 the rod 93 is moved over to bring the arm 92 into engagement with the loop 91 on the rod 90, as shown in Fig. 1. The next step in the operation is to rotate the cylinder to bring the opening l1a into line with the hopper 87 to receive a charge therefrom of sand. The operator grasps the operating rod 39 and by means 20 of said rod throws the clutch 25 into enf gagement with the gear wheel 24 which is driven by the motor to rotate the cylinder 6. When the opening 11a is directly beneath the hopper the operator grasps the lever 7 Od 25 and raising same releases one of the notches 70g and moves said lever inward to throw the trigger 702L into engagement with the notch 7 O'3 on the rim-gear. The lever is then lowered until the second notch engages the angle-plate 7 0 and said trigger is locked -in place and the cylinder held against accidental rotation. In this manner the open ing 11"L of the cylinder is'brought under the hopper 37. The gates 88 of said hopper are then opened by operating the lever 96 and the sand is discharged into the cylinder. To weigh the sand discharged into said cylinder the operator grasps the hand wheel 54 of the rod 53a and turns the same. Owing to the opposite threads on said rod engaging the nuts 51 and 53 the upper ends of the arms 50 and 52 are drawn toward each other and as the outer ends of the levers 43 and 49 bear the load and cannot rise the shafts 46 and 47 will be lifted and will carry with them the channels 45. As said channels are lifted the chairs 73 carried thereby engage the trunnions 8 of the cylinder and said cylinder is thus supported by said channels. 50 In this manner the weight of the cylinder' and yits contents is transferred onto the scale and by adjusting the weights on the scale beam in the ordinary manner the amount of sand discharged into said cylinder may be accurately weighed. Power is then applied to move the car to the next bin where the proper quantity of lime may be added in the same manner as above set forth, and then the soda-ash and salt cake. Each ingredient is weighed with great accuracy so that a uniform batch is always obtained. As soon as the exact amounts of sand and other ingredients have been deposited in the cylinder the rod 53a is turned in the oppositeI direction and the cylinder is lowered gagement with said lug 12 on said gate. The operator stops the cylinder immediately so as to leave the opening down and directly over the hopper. This will discharge contents from the cylinder to areceptacle beneath same.
